I will vouch for this one Rhys, I was amazed watching what Darren could do going into the lagoon with Dieter close behind, when it became dark and the wind picked up I thought I was in for a long (sick) night but Darrens unit and skill of use made it possible to navigate through an area he has never seen before showing marker posts and all the boats moored in the lagoon.
It was also good when we wanted to head back over to another boat (Dieter) during the daylight as we could get a fix on them from a distance on the radar and then just head straight to them
I also could read the screen without my specs on which is a big bonus, very clear and large enough to have heaps of info up at a time
